Problems solved by technology

The cabinet is generally made of aluminum alloy casting or aluminum alloy machining, but this solution has high manufacturing cost and great environmental pollution
Most of the assembled cabinets are assembled by welding process, but the precision of the manufactured cabinets cannot meet the requirements of fuel cell engines
The overall machining and forming process of the box body is very demanding on equipment, especially for systems with complex structures such as fuel cells, which are difficult to process, and there is also a problem of high cost, which is not conducive to mass production

Abstract

The invention provides a fuel cell sealing box which comprises a box body; the box body is defined by a bottom plate, a cover plate and a plurality of side plates; and sealing assemblies capable of being partially or completely connected into a whole are arranged at the connecting positions of the bottom plate, the cover plate and the side plates and among the side plates. The cover plate, the bottom plate and the side plates are connected in a sealed mode and fixed through fasteners, and a closed space is formed in the box body. The invention further provides an assembling method of the fuelcell sealing box. The fuel cell sealing box is simple in structure, easy to produce, low in cost, convenient to assemble and disassemble and excellent in sealing effect; the fuel cell can be effectively protected against external interference, and the safety of the working environment of the fuel cell is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel cell sealing box and an assembly method. Background technique [0002] With the rapid development of new energy vehicles in recent years, fuel cells are the key components of new energy vehicles. In order to improve the stability of fuel cells and the safety of the entire system, fuel cells are usually made into a sealed structure, and the fuel cells are packaged in Inside the box. This can not only achieve the effect of isolating the fuel cell from the outside world, improve its working reliability, but also improve insulation protection to prevent sharp objects from touching the charged body of the fuel cell. [0003] At present, fuel cell packages are mostly packaged in metal boxes with high strength and easy processing. The box body is generally made of aluminum alloy casting or aluminum alloy machining, but this solution has high manufacturing cost an...
